Sui stated that it has integrated SCION to protect its network validators from vulnerabilities that impact other blockchain networks.
Sui disclosed that it has implemented SCION as a defensive measure to safeguard its layer 1 blockchain. SCION has been promoted as a method to assist nodes in the prevention of unauthorized traffic manipulation.
Sui claimed that it has enhanced its resilience against DDoS attacks and hijacks by rerouting traffic from IP-based networks to SCION, an internet architecture that the World Economic Forum recommends.
SCION (Scalability, Control, and Isolation on Next-Generation Networks) is a contemporary alternative to the Border Gateway Protocol (BGP), which was developed in the 1980s and is now outdated.
SCION is a routing technology that is path-aware and offers a more effective path selection than BGP. Therefore, it enables endpoints to choose paths based on security or efficiency, thereby enabling rapid recovery from defects and granting them more control over traffic routing. Routing is also cryptographically validated between networks.
In principle, Sui nodes that utilize SCION have the ability to select from a variety of traffic routes. If this operates as intended, it should enhance Sui’s dependability and rate of performance. Sui nodes must establish a SCION appliance and connect to a SCION-enabled provider in order to implement SCION.
This feature of dual-path should assure connectivity through either traditional IP networks or SCION, thereby guaranteeing high availability.
In 2022, hackers executed a BGP hijack to steal approximately $1.9 million from Klayswap, a South Korean cryptocurrency exchange. In 2018, an additional noteworthy incident occurred when attackers directed MyEtherWallet users to a malicious server in Russia, resulting in the emptying of their wallets.
In the 1980s, the Border Gateway Protocol (BGP) was created. By identifying the most efficient path between numerous autonomous systems, it orchestrates internet traffic. Nevertheless, its antiquated design renders it vulnerable to security threats, including traffic interception, hijacking, rerouting, and DDoS attacks.
Additionally, BGPs are incapable of selecting the most efficient path for data routing, as they are dependent on the shortest logical route without taking into account other factors, such as network congestion or physical distance. This can have a detrimental effect on data security and reliability.
Blockchain networks do not depend on BGP in a direct manner. Nevertheless, certain blockchain operations, such as node communication, necessitate internet infrastructure. Exploitation of this vulnerability is feasible.
